I am running discourse(3.4.1) in the cosmos cloud

When editing the post the preview can show the formula properly.  
But after I saved the post it shows text only. Actually sometimes it shows the formula briefly and revert back to text.

I’ve tried on different browsers, reset the cache and still the same.  
There is no js error in the chrome broswer(inspect\>\>console)
